Calculate power output in kw through cross-sectional area
Air enters a turbine at 40 kN/m2, 900 C, and leaves at 10 kN/m2. The flow is reversible and adiabatic. Inlet velocity is quite low and outlet velocity is 150 m/s through a cross-sectional area of 0.20 m2. Calculate the power output in kW

Two identical blocks made of extremely hard metal collide with equal and opposite velocities. Is such a collision closer to being completely inelastic? Where does any lost kinetic energy go? Assuming it is either completely elastic or inelastic, w
The volume at the end of this process is 0.10 m3, and the temperature at the end of the adiabatic expansion is 0C. Determine: - the heat added - the heat rejected.
A battery has an internal resistance of 0.9. a number of identical light bulbs, each with a resistance of 41.4, are connected in parallel across the battery terminals. the terminal voltage of the battery is observed to be one-half the emf of the b

A simple Atwood's machine uses two masses, m1 and m2. Starting from rest, the speed of the two masses is 9.0 m/s at the end of 9.0 s. At that instant, the kinetic energy of the system is 80 J and each mass has moved a distance of 40.5 m. Determine
An air line, 500 kPa, 600 K, is connected by a valve that is then opened until a final inside pressure of 400 kPa is reached, at which point T = 350 K. Find the air mass that enters, the work, and heat transfer.
A tank contains 1 m3 air at 100 kPa, 300 K. A pipe flowing air at 1000 kPa, 300 K is connected to the tank and it is filled slowly to 1000 kPa. Find the heat transfer to reach a final temperature of 300 K.
In a heart pacemaker, a pulse is delivered to the heart 76 times per minute. The capacitor that controls this pulsing rate discharges through a resistance of 1.8 x 106. One pulse is delivered every time the fully charged capacitor loses 64.4% of i
